- Watch the last part of the video where there is a glass of water on the engine. The engine runs so smooth it does not even ripple the water. Looking at the glass on the back, you are seeing the reflection of the exhaust tubes bouncing on the flat surface of the water. The water actually does not even have a ripple.

22 gallons per mile
Made my day
At first I read this and said. Damn 22 gallons per mile. That's pretty good. Then I read it again and lmao
Rx7 guys hands are busy in pants right now!
that starter motor is having the hardest day at work...
yeah, begs the question as to why a diesel truck starter wasn't used..
I remember watching this all those years ago and being absolutely captivated at the engineering and insanity that went into something like this. And now, many years later down the line, seeing this engine being disassembled and explained over on Rob's channel is surreal. You've said it yourself Tyson, this is an art piece. I can agree to that!

Its amazing! I used to work with 12A's and 13B's and I know the potential of these engines. But this is a complete power house of an engine. Well done. I would like to hear more about it.
It's smoothness is remarkable. Congratulations!
I am not exactly a fan of rotaries, but this thing looks and sounds violent!
They make double the power per displacement as 4-strokes. How can you not be a fan of that?
Power is not everything. They eat so much oil after some time, so they don't endure for long and it costs you much more money to maintain them

I think you'll find that rotaries run on a 4-stroke cycle. You must mean reciprocating-piston engines. Even then, it's pretty hotly contested how a rotary engine's displacement should be measured.
TheOfficialKC Because apex seals.
TheOfficialKC
rotaries are 4 strokes, but you are correct about the volumetric efficiency
i want to see it in a car
making a time machine or somethin?
Actually we built a time machine first, then went back and got Felix Wankle and brought him up here to our time and he built the engine.
I'm not a car or engine geek but that's a work art.
Let's see what Rob Dahm can do with this puppy...
Mazda should've had you guys in charge of their R & D division ! I still can't believe they stopped production of their main Rotary instead of continuing to try and refine it.
sweet fucking jesus that craftsmanship.
I bet it's faster than Sanic
Getting closer, well done, will be a beast once its up and running properly!
This engine is simply a technological masterpiece, you have done well! I'm curious what rpm this wankel monster can roar to... guess it's time to check out your channel!
Looks great but should invest into a mega squirt efi setup (of possible) because the carb is so far away from the front that it has to be leaning out the front rotors.
Working on it
Over all I have to say nice looking engine.
YOU HAVE NO IDEA HOW LONG I'VE BEEN WAITING FOR THIS~~~~~~~!
Solid engine ;) I want to see this in any vehicle ASAP
Please keep the videos coming
I recall back in the 70's Mazda had in their commercials the slogan, "Piston engines goes 'Boing, boing, boing' but the Mazda goes 'Hmmmmm'." This rotary engine isn't going 'Hmmmm.'
Water barely moved! That's some good machine work there!
this is 1 of the coolest engine i have seen on the net, when i look at this i see the rotary engine like a 3 cylinder engine and there are 12 so to me i see like a 36 Cylinder engine and i think that is kind of amazing
I like the state-of-the-art exhaust evacuation setup they have. Looks like something I'd do.
Well done, sir!
This thing looks like it could launch windows 98 or cut through time. Wow
Can't wait to see how things ends!
someone really knows there stuff! thanx for the pic on the porting, post some pix or video if you decide to put down in a car would love to see that!
This is meant for a drag boat? Aw, and here I was hoping it'd go into a top fueler, it'd be insane to hear going...
Just take my money and give me the engine
that is fantastic, I love the WANKEL!
I love the engineering behind this but the best part is it doesn't sound like a rotary :-)
yea it does it sounds like a 12 rotor rotary
Thats the worst part. Needs more brap brap.
Ryan Holmes Nope, it is not a primitive muscle car V8 but a brutal 12 rotor wankel with a great sound. ;)
ckb313235 *Facepalm* Peripheral Ported wankel engines go brap brap. Muscle cars go blub blub.
"FrankenRotor" Damn.
That is a thing of beauty!! I see you're working on tuning the fuel delivery. . Once finished it will be insane! What sort of car will sport this sinister piece of work? Huge props on building know how good sir
Nice work. Four banks explains the shortness of the block. The C111 engine was at least 2 feet long, maybe longer and that was 4 rotors. Couldn't imagine putting a 6-7 foot long engine in a 1970 FIAT 500. ;)
Andrew Gems Oh yeah... or a Hudson Hornet. :)
Now you gotta go get an RX7 to put it in lol
Adaptronic E1280S will be at your door soon!
I would really love to see one of these engines mounted to a top fuel dragster frame. Holy crap. Put them up against one another if its making over 9k HP!!!
Well done guys awesome acheivement ,please let it actually go in some sort of machine
Thats the way my cup of coffee looks in the morning.....
damn nice engineering
Complete ground-up design or based on Mazda's rotary ?
I love seeing people actually deal with rotary , that's one interesting ICE !
It is awesome to see 12 Rotors engines that works, but what are you accomplishing in these era with several altered ways into the Hybrid future.
impressive
That's an awesome chromed up version of a rotary engine, I only see four exhaust pipes coming from it on one side so it would be a 4 rotor engine right? Or does it have three E shafts in a W configuration? It looks kind of like three 4 rotor engines put together side by side. Please show a diagram of how the engine is assembled.
Fuel efficiency like " Look I am Volcano now"
that's insane!
I see what you did. Interesting.
Well... Fuck. My 12a isn't going to keep up with that now is it..? LOL!
What's truly surprising is that for the first 1:09 when they were trying to get it running that no one die of CO poisoning. Because an engine puts out a lot of CO and in a confined space it really does not take long for the CO emissions to build up. That is why a "Garage Under house is dangerous. Because if you go out on a cold morning and don't open the garage door, that room will fill with enough CO to set a sensor of in only a few seconds to maybe a minuet depending upon leaks from bad seals around the garage door and so on. it is also advised that if you have one of those types of houses to shut the engine off and leave the garage door open for a few seconds before closing it. It is truly amazing how fast CO emissions build up in confined spaces! Be careful.
I need like two of those
It a Puerto Rican's dream !!!
Haci mismo es ;)
Fucking Beautiful
wow there's hardly any vibration. definitely built with care.
Stunning piece of engineering! Did you cast or machine your own parts?
we machined it all out of billet
Hello there, what's the configuration on this monstrosity!? What's your end game? How are you firing the ignition? Do you have 3 different independent crankshafts joined by a chain or something along those lines?
Wow!!
Bad ass engine, but mpg would literally be like 1.2 mpg. lol Nonetheless bad ass.
That's not water... it's clear gelatin! :P Just kidding... Smooth engine. I noticed the three banks of rotors and that is very impressive. I'm curious how you tied all three rotor banks together into a single output shaft?
TUUUUUUUURRRBBBBBBBBOOOOOOOOOO!
UNIT!!
So many rotors doesn’t even sound like a rotary engine.
You have injectors directly into each combustion segment? What was the carb for?
damn sounds like a muscle car engine... cool
Awesome masterpiece this. Imagine timing this beast.....
Holy f#ck that would be frustrating!
Dyno run please!!
If I remember right, it hits 800+ lbs of torque at 3200-3300 rpms, capable of going as high as 14000 rpms for drag racing (boating I believe.) This is meant to replace big block Chevy engines in racing, and I am all for it being a big rotary fan for years.
Matt Pierce
id love to watch a big block run its mouth against this rotary lmao, Long live the Rotary!
Kurt DEz I cant say nothing against this engine but ROTARY engines have a piss poor reliability rating, im not talking about this one im talking in general and my HEMI purs like a kitten pretty sure you can do your water glass test on my big block too !
I can almost guarantee that it won't be nearly as smooth as this rotary, if it is, please post a link to a video, I would love to see it
Challenge accepted ! :P
this thing sounds like its angry to be awake
what is this beast going in?
BRAP BRAP BRAP
intake/exhaust look like they are designed for a boat?
I wonder if this can be applied for a turnkey replicas? The small size engine and tremendous power will be great for all replica enthusiasts around the world. Can I buy this engine for my lambo replica? How much if you do sell one?
Lol you was so eager to put this engine into life you just put a hole in the garage door for exhaust!
pretty sure they didn't want to black out and die lol
its pretty clear to see the intake manifold and the 2 exhaust manifolds ...... you goon lol
Put this monster running on hydrogen and a turbo. You can forget about the P1 and all the fancy hybrids for the next 60 years.
No revs?
0:31 start!
hope its running e85
Are there gears on the end of the 2 E shafts of both sides connecting to a big E shaft in the middle? I'm quite interested in how this thing works.
if u notice.. this is infact 3 banks ofr 4 rotors. there are 4 ports on each side to the middle lower back is also 4 rotors.
Robert Read
All that engineering and I see a carby on the motor? C'mon guys.
umm im not working on that engine.. im just using my engineering eyes to work out how it works ;)
Robert Read it looks like he figured out what you said, and i want to know the answer to his question too..... Chain driven maybe? or it would have to be geared?
well the left bank and the middle bank rotate clock wise as the right bank rotates anit clock-wise and probably use timing gears to keep it that balanced and timing belts and chains have a lil back lash that will mak it run no so well balanced. i could be completely wrong about this but i am just using my knowledge of rotary engines and looking at the ports on this thing.
Big yellow cat .. I'v watched this going on for a while now .. have you tried it in the cat yet
What are they going to put that monster in
Will this fit my Honda M8?
Wow! What is the HP on that guy?
I am confused theres no exh, int or combustion stroke some technically isnt say a 1.3 a 3.9?
I see there's only 10 pipes in the intake and 8 pipes in the exhaust. I'm very confused because this engine sounds more like a 10 or at least an 8 rotor
there are 12 rotors, the center intake pipes are split to the rotor on each side. If you look close you will see the exhaust from the center rotors coming up to each side so there are six exhaust pipes on each side.
how much does it weigh
upcoming Mazda RX9 2016
wow O.O
imagine trying to chase a misfire on that.
Now.. TWINCHARGE IT :3
Put that in a dune buggy or in a drag car with like a 100 mm turbo
I only see 10 pipes in the intake manifold, are there shared cylinders or something?
First off, it doesn't have cylinders, it has rotor housings. The way this is set up is 4 rotors in the middle, and another 4 on either side. The port closest to the front of the engine is actually an exhaust port shared by each rotor in that section, on the right and left side, I'm pretty sure the two median rotors share the same intake port. That explain everything for you?
Okay, right, scrap that, I figured it out. The intake manifold is the massive cylinder we see in the middle, it feeds to each and every Rotor, the manifolds on the right and left sides that I thought were for intake are actually exhaust manifolds. Didn't get a good enough look to know for sure, but I think they feed into the rear section of the intake which I'm assuming is sealed off, and that's where the exhaust leaves, that's what the two ports at the back are for. I didn't design or build it, this is just an estimation.
Wait, no, last one I swear, somehow it seems all the exhaust is sent to that manifold on the right, it might also exit from the left, I can't really see.
Yeah, all the exhaust goes to the left and right manifolds. Jesus Christ that took me a while to figure out. Sorry for spamming your notifications.
+MaxTheKanuck #JoinTheMasterRace on our boats we usually have two exhaust openings in the back so I made the center rotors exhaust to the left and right sides. If you did not know what I was doing the intake and exhaust piping would be hard to follow.
Nothing quite like a power stroke every 10 deg. Lol
The oil it will use...
how much hp
what rotors ? mazda ?
Hey is the i s a Tvelve rotor wankel mounted like this
Jesus how much hp does.this make and what Gearbox do you have to have and the price?
Its a shame the video doesn`t give you the real sound of it.
definitley
That's a pretty expensive way to boil water...
Defiantly an "A++" for creativity and ingenuity, but, seams that he is having a hard time getting the thing to stay running. I am by no means an educated person when it comes to Rotary engines, but, I have to say that from what I have come to understand of the Rotary engine is...it's kind of like an inline engine. so to make one into what looks like a " V " configuration, what kind of engineering goes into taking an inline engine and making a mirror image or it on the other side then getting some sort of gear box that would take the two in line's and make them "come together" to work a " V " configuration and have it spin at the same rate as the Rotary's are? I know that there are 2 types of superchargers, a "Root style" that sits directly upon the engine intake manifold, like In Top Fuel. Or a Centrifugal device that uses gearing ratios to make it spin faster than the engine speed in order to build up pressure and those are mounted to either an existing bracket on the front of the engine and perhaps making you swap out your lower Crank pulley to accommodate the new item or some that say just get a bigger "serpentine belt" in order to make it work. Either way there is a set of gearing that is involved inside the S.C. that makes it work. So that is what intrigues me the most about this particular set up? How do you get those two to work together, and maybe that is the crux of the matter, that issue is what is holding this BEAST OF A ROTARY ENGINE FROM WANTING TO WORK PROPERLY? I would love to know how you did this Mr. Garvin, please tell me, unless you are under the "paten pending" process and that would prohibit you from "spilling the Proverbial Beans". LOL. Anyway, cool build man really cool, as I said I would love to know how you got those two to work "together" perhaps you could do some of that magic on Capital Hill! Lord know they NEED IT!!!!!!
I have a gear box in the back of the engine that ties the three cranks together. The center crank is the output. We made the bank on the right spin the opposite direction so the engine would look symmetrical by having the exhaust ports toward the outside on each side. On having trouble getting it to stay running? That was the first night we actually tried to start the engine, I wonder how long it takes gm to get the first engine they ever designed from scratch to start? Probably more then a few minutes.
That's slick!

Hello jhon?
Hello Mr. or Ms. Zailani. I say that because I don't know if "Faisal" is male of female. Please forgive my ignorance! plus, there are 2 people in the pic so I don't know who is who. Sorry.
I got 10 rotors? !0 pipes coming out for the exaust? Weird though... it looked like there was 10 pipes for the intake, but a couple more, looked like they where going to the crankshaft?
Geeez, it's just as big as a big block V8... Guaranteed to leave one of those big blocks in the dust... dude would be like "what just happened"?... he'd be just taking off at the starting line while the dude with this engine is already packed up and on the road home!
this is really cool! Just curious is it possible to do some porting. such as a bridge port?
this is what they did with the porting: www.performancegarage.com.au/sites/default/files/blog-content/r122.jpg
RetardedGoat16 OK all I can say is wow,and it would be amazing if mazda picked up development of rotary engines again.
RetardedGoat16
Cool picture. It's still side-ported, but with pretty big side ports.
Looks like it may have cooling problems when he finally gets it up to power.
